But nobody can deny the reality for the long run, and fossel fuels aren't going to disappear.
Anyway bitcoin can be mined with green energy sources , when their price becomes sustainable and competitive
How long do you define long run? Fossil fuels are being taken out of the ground 10 million times faster than they were put in - and their usage increases every year. The long run isnt as long as many seem to imagine IMO.
